MACHINE FOR FORMING PAPER CONES.

SPECIFICATION forming part of LettersPatent No. 549,474, dated November 5, 1895.

Application filed July l0, 1889. Serial No. 317,100. (No model.)

To @ZZ whom it may concern.-

Be it known that I, JOHN J. BORDMAN, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Machines for Forming Paper Cones, of which the following is a speciiication, reference being had therein to the accompanying drawings.

Figure 1 is a side elevation of my papercone-forming machine. Fig. 2 is an elevation from the opposite side. Fig. 3 is a top plan view. Fig.4 is a central vertical section. Fig. 5 is an elevation from the outer end. Fig. 6 is a view, partly in elevation, partly in section, through the center of the revolving carrier. Fig. 7 is a section of the blank-holder,the mandrel, and the pressure devices. Figs. S and 9 are views of the two faces of one of the camwheels. Fig. 10 is a perspective of one of the stops. Fig. 11 shows the'mandrel detached. Fig. 12 shows three cross-sections of the mandrel for full size. Figs. 13 and 14 are side views of the operative end of the mandrel. Fig. 15 shows a spring friction-washer. Fig. 16 is a perspective of another cam. Fig. 17 is a section of the air-chamber and valve devices. Fig. 18 is a face view of the paper blank. Fig. 19 is a longitudinal section of the paper cone. Fig. 2O is a longitudinal section of the cone, showing a coiled wire inserted. Fig. 21 shows detached the spring-catch which holds the cone-carrier from revolving, and also the device which intermittingly releases said catch. Fig. 22 is a plan view of the devices for discharging the cones from the carrier. Fig. 23 shows the former and the adjacent parts in their first position. Fig. 24 shows them just as the paper cone is being taken off.

The initial power-shaft is indicated by A, it being provided with a fastened band-wheel A/ and a loose wheel A2, and being mounted in suitable bearings a (d.

A3 represents the bed-plate of the machine,

which may be of any suitable character, and

from which rise standards for supporting the operative parts.

Shaft A has a pinion d2 for transmitting power-to the second shaft B through a gearwheel b secured thereto. The shaft B is mounted in bearings in the standards B3 and at B', the latter bearing B being carried by a collar B2, supported on a shaft rising from a standard B4. The shaft B carries, among other things, a wheel o', which is feathered to the shaft so that it can play slightly therein longitudinally. It is held in frictional contact with a bevel-toothed wheel b2, pressure being exerted by means of a spring b2 bearing against a collar b4. The wheel b2 engages with the bevel-wheel C2 on a hollow shaft C. The operation and the mutual relations of these parts will be more fully described hereinafter. At present it will be noted that the revolving cone-carrier O is intermittingly stopped and prevented from rotating for intervals by means of a catch-bar D, having a catch d, normally pushed upward by means of a spring d, the bar D being fitted and sliding in a guide D. The catch CZ engages with notches c in the carrier O. The rod D is provided with a lug d3 at the lower end, with which a cam cl2 on collar B4 on shaft B engages. V'Vhen the cam comes around, it engages with lug cl2 and for an instant pulls and holds down the catch d', whereupon the friction between the parts b and b2 is efficient in causing the rotation of the wheels b2 and O3, and the carrier C; but when 'the cam d2 disengages from lug d2 the catch d takes into the next notch c, and the carrier C is again held stationary for an interval.

On the shaft B there is awheelE on a loose sleeve or hub, (see Fig. 4,) having a cam E', through which the motion is given to several of the parts as follows: Cam E bears against an arm E2, having an antifriction-roller e, this arm being secured to a sliding bar E3, mounted in guide at e. Bar E2 is pivoted to a lever F at e2, and the lever is in turn pivoted to the standard B3 at f. At the upper end the lever F is pivoted by means of a short arm at f to another sliding bar G, held in guides g g'. A weight at F2, secured to an arm f4, tends to swing lever F outward around the pivot f-that is, to hold the arm E2 and the roller e against cam E'-and insures a movement the reverse of that caused by the cam.

Lever F has at the top a cam-like projection F', for a purpose to be described. The bar g3 is secured to bar G and extends to the centra-l vertical plane of the machine, where it is provided with a sleeve g4, which is secured to the cone-forming mandrel H H'. There is a spring g2 around the sliding bar G, bearing against the guide g' and the bar g3. Then the lever F is moved forward by the cam E' the mandrel is caused to slide forward. The spring g2 assists in keeping the parts in proper relation to each other.

The part H of the mandrel is a cylindrical bar adapted to both slide and to be intermittin gly rotated. The part ll' is the fru stum of a cone. These parts are solid, except that they have a groove 7L' 712 extending in from the peripheral surface. The end of the paper is received therein when it is to be wrapped, it first entering at 7:', which is made wide to insure an entrance.v In the groove there is a swinging or vibratable gripping-iin ger h3, actuated b'y spring h5. I have shown a form, which for some reasons I prefer, wherein a swinging linger and the 'spring are integral, being secured in place at h4; but it will be readily understood that the spring and the linger may be separate parts if desired.

The mandrel and cone-former move longitudinally with the parts above described-to wit, those at E2, E3, F', and G.

The parts which intermittingly rotate the forming-mandrel are the following: J is a wheel loosely mounted on the shaft B, it hav ing a sleeve j. It has, however, a constant tendency to rotate with the shaft B, because of the presence of spring-washers ,js interposed between the wheels b and J, (see Figs. 2, 1l, and 15,) those shown being wooden blocks 72, pressed against the wheel J by means of spring plates j", both held in place by screws jl. This tendency to rotateis overcome during proper intervals by means of a catch l72, adapted to engage with a bar 7c, which bar is held in the path of the catch by a cam K on wheel E. As soon as the cam turns away from the bar 7l', a spring 7c' 'slides the bar out from the path of catch y2, whereupon the friction between wheels b and J is eflicient to cause the rotation of wheelfJ. The catch is carried by an adjustable hub J', fastened by screw j' around the sleevej. The wheel J engages with a wheel J2 on sleeve J3 around the shank part II of the forming-mandrel, the latter being connected to t-he sleeve J 3 by fea-ther and groove, so that the mandrel can slide and be at the same time rotated, or slide when the wheel is not rotating. It will be seen that the forming-mandrel can thus be given two motions, either simultaneously or independently. The mandrel is mounted in the laterally-extended bearin g B5 at the upper end of standard B2.

I will now describe the devices by means of which the paper is fed to the mandrel.

L is a shaft mounted in a bearing at Z and having a wheel L', driven by wheel I), and a wheel L2, which engages with a wheel M' on shaft M in a bearing m. The shaft M has a wheel m2, which engages with the aforesaid wheel E. The latter is carried by the aforesaid sleeve or hub of wheel E, which at the other end is secured to a cam-wheel N, the periphery of which is throughout a greater portion thereof circular, but which is cut away at n. This acts to alternately lift and hold up on the one hand and on the other allow to drop a rod O, which `is secured to a valve O5. This valve is mounted in a tube O, having an inlet O3. The tube OG communicates with a chamber O' and has an exit duet O, adapted to be connected with an air-pump. The rod O is mounted in bearings at o2. The camwheel N engages with this rod through an arm o, adjustably fastened by a collar and set-screw at o'. A hose or other pipe O2 extends from the inlet o3 to a pipe O3, which is secured to a rocking arm S. The pipe O:z at the bottom has an expanded plate or sucker OT, (see Figs. 3 and 7,) and when an exhaust is applied to the chamber O' there will be suction caused through plate or 'sucker O7, tube O3, hose O2, inlet o3, and outlet Ol-that is to say, this will occur if the valve O5 be in such position that its port registers with the inlet 03.

The machine, as shown, is provided with parts which supply blanks previously cut; but I do not limit all of the parts of the machine to the specilic means for supplying the blanks, asat this date numerous' devices are known for accomplishing this.

I have shown a holder P adapted to receive `several hundred blanks cut into the proper shape, theshape of this holder conforming approximately to that of the blanks. These rest upona movable bottom P', against which pushes a rod P2, held in a guide pl. The rod P2 is pushed upward by means of a cord p passing over pulleys p p2, and having a weight p2 attached to it. These devices insure that the top blank of the series shall always be held in contact with the bottom of the sucker or 'suction-plate O7. The holder P is placed by the side of the mandrel H Il', one end thereof being more or less nearly parallel to the axis of the mandrel. The side wall is cutaway a little at P5, so as to form a throat or passage for the blanks. or suction-plate O7 is intermittinglyvibrated toward and from the mandrel, it being carried by the pipe O3, which is secured to a rocking arm S. Thelatter is pivoted to a lever S', which by a link S2 is connected to a slide S2, mounted in a guide s.

S4 is a link connecting the slide S2 with a vibrating lever S5, pivoted in an upright S s' s2 are projections extending down into the path of the above-described extension F on lever F. As this lever F oscillates, it alternately strikes these projections, and through theseries of levers, links, and slides from S5 to S moves the suction-plate o7 first away from the mandrel toward the end of the The sucker' IOO blanlcholder and then back toward the mandrel. At the instant that the suction-plate `reaches its outermost position an exhausting of the air from the hose 02 and' tube o3 is caused by the means above described, and therefore the top blank of the pile is sucked and held against the plate 07, and this suction continues while the suction plate and pipe o3 are moving through their returnthrow toward the mandrel. The plate therefore in coming back slides the top blank through the throat at the inner edge of holder. At this time the mandrel is moving outward away from the part C and is not rotating, and the end of the blank is pushed into they enlarged part 7L. as it moves past the throat P5 of holder P; and the mandrel, continuing to slide backward the end of the blank, is crowded into the narrow part h2 of the groove, where it is firmly clampedvby the spring-finger h3. At the instant the blank is properly seated in the groove the suction is stopped and the operation of wrapping begms. Y

Any preferred material can be used for causing the blanks to retain their conical form after wrapping-that is to say, use may be made of any suitable adhesive substance for causing one fold or layer of paper to ad'- here to the next. Paste of suitable kindmay be applied to' the edges or over the whole surface.

For making the larger and heavier cones, such as are adapted for holders for cigars, I prefer to employ a strong binding or adhesive material, such as the substances which require heating'in order to soften them. In applying an adhesive substance of this sort Input it upon the paper while it is still in sheet form and cut the blanks afterward, as this is the more economical plan. If the adhesion be one of the sort requiring heat to cause it to act I employ devices as follows, in conjunction with those above described:

vT is a pressure-plate situated opposite to the throat of the blank-holder P and opposite to the conical former or mandrel when in position of wrapping. This plate normally tends to move with a yielding pressure toward the mandrel, so that the paper, while being wrapped by the mandrel, Y will be tightly gripped on the outside. It is pivoted at t4, and is pressed forward by weight tand lever t t2, pivoted at 158, there being a stop at t5 to limit the movement.

This pressure-plate or its equivalent is used in all cases-that is to say, I prefer to apply a pressure to the paper as it is being wrapped for the purpose of smoothing down the folds one upon the other and packing them tightly in place and causing the adhesive substance to get irm hold. When heat is to be util# ized, as aforesaid, I form a chamber immediately back of this pressure-plate, preferably by side walls T T, a top T2, and a rear wall T3. Inside of this chamber or below it there is situated a heatgenerator, suchl as agas burner, or burner adapted to hold a wick or one capable of vaporizing a light oil. The letter U `indicates the same, u representing a part of the supply-pipe.

c In operation, the pressure-plate is highly heated and as the blanks are successively wrapped upon the former the side having the adhesive material is softened and under the pressure is caused to enter the pores of the paper and produce a rm fastening of one fold upon another. After the cones are formed upon the mandrel, the latter advances toward the part C, which is formed with conical apertures or sockets c', whose walls conform to the peripheries of the cones. The paper cone is thrust by the mandrel snugly into one of the said apertures or sockets and immediately thereafter the mandrel slides back to the position for beginning another operation, leaving the paper cone in the socket in the part C. Before the mandrel returns with the nekt cone the part C has been released for an instant and advanced one step,so that an empty socket is presented. To'insure that the cone shall be left in the socket and not drawn back by the mandrel I combine with the abovedescribed parts supplemental devices to assist in taking the cone from the mandrel, they consisting of a plate or block I, having a concave upper surface, a rod carrying said part l and fitting in a guide 1", and a spring t2, which tends to push the part I upward toward the mandrel. This plate or block I engages with the larger end of the cone, it preferably slipping behind the edge of said larger. endjust as it reaches its position in the socket c". Then when the mandrel recedes it is ordinarily impossible IOO for the cone to come'back, but is forced from f;

the mandrel, the latter slipping from the inl' terior. A y

By retaining the cones in a device of the nature of that at C they are kept under pressure at a number of points on their periphery or around thewhole of it for a period of time after the final wrap has been finished, and the paste, gum, or other adhesive substance is allowed time to set and harden. Instead of this the cone may be discharged loose at once from the mandrel into a suit able receptacle.

When a tempory holder is used, l combine with it a suitable mechanism for linally releasing and throwing out the cones. As shown,this consists of a push-rod R, mounted in a sleeve-guide R', slotted at r. The rod R is intermittingly reciprocated on lines radial to the carrier C by means of a link R2, pivoted toit at r', the pivot sliding in the slot r, and the link R2 is pivotally connected to the crank R8 on a rock-shaft R4, mounted in a bearing at r2. At the lower end shaft R4 has a crank R5, pivoted to the link R6, which is also pivoted to the arm r3, secured to the above-described sliding power-rod E3. When rodl]3 'is moving toward the carrier C, it, throughlink R6 and crank R5, rocksshaft R4,

IIO

and the latter, through crank R'nl and link R2, causes the push-rod R to slide in the guide R; and this guide and push rod are so arranged in relation to the carrier (l that when the rod R is to operate on a cone it lies opposite to and in line with one of the holders c, so that the rod on entering the inner end of one of the holding-cavities strikes against the small end of the cone of paper and pushes itoutward.

"With the devices above described I can combine means for applying a spirally-bent wire to the interior of the paper cones and fastening the wires therein. rIhis is done in manufacturing some sorts of holders for cigars, although it is an operation that may be omitted in making holders of other kinds.

I do not herein claim my improved meehanism for performing the operation requisite to insert the wire, and therefore do not describe the same herein, being about to file a separate application for that subject-matter.

I am aware of the fact that paper-wrapping machines have been used in each of which there was a forming-mandrel and a pull-off mechanism, the latter bein g generally of the form of a ring and. supported stationarily around the former at a place inside of the end of the paper cone or tube, the mandrel being adapted to move from its first position, or the position of wrapping, backward toward and past the pull-off. In my case the pull-off I is normally situated at or outside of the small free end of the mandrel, said mandrel and pull-off being arranged and related in such way that one can movetoward the other until the pull-off is situated behind the large end of the paper tube or cone. An arrangement of this sort makes it possible to deliver the paper cones one after another to a receptacle having a receiving chamber or chambers.

I herein refer to the fact that after the blanks have been wrapped on the conical mandrel, and after the heated or softened adhesive has been applied to them, they are subjected to external pressure while being supported on or in an intermittingly-inoving carrier. For the application of such external pressure I do not limit myself to the exact devices shown-namely, the conical walls of the chambers c in the carrier C, though for some purposes I prefer such walls, as they can be caused to hold the layers of paper together until the adhesive is cooled or hardcned.

I am also aware of the fact that in the manufacture of long paper tubes use has been made of mandrels supported at both ends, said mandrels being mounted above vats or vessels containing bituminous materials and heaters to melt or soften the same, and I do not claim such devices as of my invention; but I believe myself to be the first to have so arranged the parts that the paper cone can be automatically formed and have heat applied to the adhesive therefor, while the-mandrel is revolving in proximity to a non-revolving pressure-plate, and then have the mandrel carry the cone to an automatically-actingpull-oif,which causes the removal of the cone from or over the 'free end of the former.

ly having a spring gripping-iinger arranged in the way described and shown it coacts advantageously with the yieldin g pressure-plate in holding the paper properly during the wrapping, and when the pull-off is engaged with the cone this gripping-finger allows the gripped part o'l' the papers to escape easily.

At this date some cone-making machines are known in each of which the mandrel is moved longitudinally relatively to the pulloff or ejector, as at I, and in others the pulloff has been given a longitudinal movement relatively to the mandrel, and hence all ot' the features of the present invention are not limited to the exact details shown, inasmuch as a mandrel having features similar to thatlierein can be used with a modified form ol.' pull-off. Again, in some of said machines provision was made for applying both a coating of wax, and also more or less paste, and when Iherein refer to adhesive material and means for heating the same I include such machines as coming within the scope of my invention.

l.. In a machine for making paper cones, an intermittingly revolving circular cone carrier having a series of holders adapted to retain the cones under pressure and an. intermittin gly actin g ejector arranged within the cone carrier and adapted to engage positively with and bear against the cones to remove them from the holders, substantially as set forth.
